PORTABLE VARNISH-DRYING OVEN.

To all whom it may concern .1 I

Be it known that I, WILLIAM O. Goren, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Portable Varnish- DryingOvens; and I do hereby declare the following to be a full, clear, andexact description 'of the invention, such as will en able others skilledin the art to which it appertains to make and use the same. Y i

This invention relates to varnish drying ovens and while particularlyadapted to varnish drying ovens for automobiles, is not limited thereto.

An object of this invention is to provide an oven for drying varnish onautomobiles and especially where successive coats of varnish are appliedto automobiles and where it is desired to apply varnish to automobileswhich under ordinary circumstances would require as high as three weekstime in order to dry the respective coats of varnish and this isespeciallv so in cold weather and weather unadapted to the drying ofvarnish after it has been applied.

It is an object of this invention to provide a portable oven which maybe quickly enveloped around an automobile and to provide a means forvarying the heat and for keeping a constant desired and predeterminedtemperature, and to provide further means for causing the flow of theheat into the said oven under the desired conditions.

It is a further object of this invention to provide anelectrical heaterfor varnish drying ovens and to provide a means for controlling thetemperature of the said electric heater and the temperature of the airpassing thereover.

It is a further object of this invention to provide a means for blowingheat into a varnish drying oven in order to provide heat therein from asimple heater, and a detachable and portable oven and to provide it forfurther purposes in relation to said blower.

It is a furtherobject of this invention to provide a quickly knockeddown and portable varnish drying oven for automobiles and the like, andalso to provide a quickly detachable and easily portable heating means.

It is a further object of this invention to provide a varnish dryingoven and heater therefor in such separate units as will makeSpecification of Letters Patent.

it heatable and readily portable and adustable and adaptable to varyingsized cars. WV th these and other objects in view the invention consistsof the construction, the combination and the detail and arrangement ashere nafter more fully described and claimed.

Figure 1 is. a perspective of the varnish dry ng oven together withheating attach- Iment therefor.

Fig. 2 is a plan view of the varnish drying oven.

Fig.3 is. a fragmentary side section showing the connections of the saidoven with the seats of an automobile.

Fig. 4 is a diagrammatic view of the heatmg system.

In detail the invention comprises an oven A, an electric heater B and ablower C. A conical conduit 2 connects blower C with heater B and aconduit 3 connects heater B with oven A. Heater B is suitably mounted onrollers 4.- detachable from conduits 2 and 3 by relative movement. OvenA is made up of sections 5 and 6 and top sections 7, 8, 9, 10 and 11 andinterior sections 12 and 12. Side sections 5 and 6 are relativelyclamped by wing nuts 13, thus providing for the suitable insertion ofthe top sections. These sections are variable in accord with thedifferent sized automobiles, as for instance the sizes of automobilesmay be accommodated.

From oven A is also provided a vent pipe 14. Blower C is provided with amotor 15 driving a fan 16 having preferably suitable electricalconnections 17, but it is obvious that the fan may be driven by anyother unit. Heater B comprising a hot plate of preferably resistant formis insulated in the usual manner and controlled by a rheostat 17, whichrheostat controls the electrical current from any suitable electricalgenerating system 18.

Thus it is obvious that in operation all that is essential is to operatethe fan in the blowerC causing a draft to go through the funnel shapedconduit 2 over the heater B and into the oven A and regulate the same bysuitable governing of the fan 16 and the heater B.

.In some cases I desire to vuse the electric heater-inside of the ovenWith the aid of the fan particularly to circulate the heat andby thismeans I am enabled to conserve electricity.

What I claimis: I

1. In combination, aboz; havingamotor therein, a fan onsaid m or, avehicle-carrying-an electric heater collapsible varnish drying oven,a-condu 'it from the heater to said oven-and a conduit from theblowertothe heater.

2. In combination, a portable varnish dryingsoven comprising. side vvallsections, and

means for clamping tlfe same together, a plurality of top section's, apipe from said oven and means for 'bl'owingheated air into the oven;

In. combination, a heater,-- a'blower, a funnel=shaped conduitconnecting the blower and heater, a collapsible varnish drying oven,and; a'cond'uit from said heater into the varnish dryingoven. v

4. Incombination, a portable-varnish dryin'g' oven, a vehicle carrying aheaterhaving a conduit leading into said oven and a de- .ta'c'l1ableblower having a c'onduitleading intosaid heater.

, 5., In combination, a box having a-motor there1n,a:fan on said motor,a vehicle carry ing an electric heater, a collapsible varnish dryingoven, said oven adaptable-t0 receivean automobile, aconduitifromsaidheaterlto saidv oven and a conduit from said blower 'to saidhe'ater.

6.11111 combination, aportable varnish dry ing ove'n for'automobiles;comprising side Wall sections and means for clamping thesame together, a plurality of top, .section adaptedto fit, around anautomobile, a'feed pipe from said oven, and means for blowing I heatedalrinto saldoven.
